Description

A rainwater collection and treatment device

technical field

The utility model relates to the technical field of rainwater collection, in particular to a rainwater collection and treatment device.

Background technique

Rainwater is a precious water resource. The collected rainwater can be used for greening, flushing toilets, etc., which can reduce the use of urban tap water and achieve the purpose of energy saving and environmental protection. However, rainwater will absorb dust and impurities in the air during the whole process from generating, falling and falling to the ground. In addition, when rainwater falls on the ground and flows into the rainwater collection device, it will also affect the surface of objects on the ground. The dust and impurities are adsorbed, which will cause rainwater pollution and reduce the water quality of rainwater. The prior art often ignores the serious rainwater pollution in the early stage of rainfall when performing rainwater collection and treatment. Direct collection and treatment will pollute the relatively clean rainwater collected in the middle and later stages of rainfall and increase the difficulty of treatment. Therefore, it is necessary to propose improvements to the prior art.

Preferably, in this embodiment, the inner side of the shunt pipe 5 is provided with an inner cavity 16, and the outer periphery of the inner cavity 16 is provided with a piston one 12 and a piston two 13. A water outlet chamber 15 is arranged between the first 12 and the second piston 13. The side of the water outlet chamber 15 is evenly distributed with a plurality of through holes communicating with the outside. The other end is connected with the inside of the shunt pipe 5; the lower part of the shunt pipe 5 is connected with a branch pipe 7 and a branch pipe two 8, the branch pipe one 7 is communicated with the abandoned flow cavity 6, and the branch pipe 2 8 is communicated with the treatment cavity 9 .

Further, the treatment chamber 9 is provided with a second filter screen 10, and the aperture of the first filter screen 2 is larger than that of the second filter screen 10; the second filter screen 10 further filters the rainwater entering the treatment chamber 9. The lower end of the side is provided with an outer pipe 11 , through which the disinfectant rainwater can be fed into the treatment chamber 9 for treatment, and the treated rainwater can also be released through the outer machine pipe 11 .

Further, an inclined table 3 is arranged below the filter screen 1 2 , and the inclined table 3 is connected with the shunt pipe 5 to facilitate the inflow of rainwater into the shunt pipe 5 .

Further, the diameter of the first branch pipe 7 is smaller than that of the second branch pipe 8 , so that the rainwater can be smoothly discharged through the second branch pipe 8 when the rainfall is large.

The specific materials of the first piston 12 and the second piston 13 are not limited. Preferably, in this embodiment, the materials of the first piston 12 and the second piston 13 are rubber.

The working principle of this embodiment is:

When it rains, the collection chamber 1 collects the rainwater. In the early stage of the rainfall, the rainwater is generally seriously polluted and the flow rate is relatively small; the initial rainwater is filtered by the filter screen 1 2 and then flows into the shunt 5 from the inclined platform 3. Because the rainwater flow rate is small , Under the action of the return spring 14, the rainwater reaches the water outlet cavity 15 through the inner cavity 16. At this time, the water outlet cavity 15 is connected with the branch pipe 1 7, and the rainwater with more serious pollution flows into the waste flow cavity 6; The rainwater has a greater impact on the second piston 13, so that the second piston 13 moves in the direction of the compression of the return spring 14. At this time, the first piston 12 closes the branch pipe 1 7, and then the water outlet cavity 15 is communicated with the branch pipe 2 8, and the rainwater passes through the branch pipe. The two 8 flow into the processing chamber 9 . After the rainwater stops, the filter screen 2 10 further filters the rainwater. At this time, the disinfectant can be introduced into the treatment chamber 9 through the outer pipe 11. After the disinfection is completed, the rainwater can be released through the outer pipe 11 for use.

Example 2

In Example 1, the disinfectant is introduced into the treatment chamber 9 through the outer pipe 11, and after the disinfection is completed, the rainwater is directly released through the outer pipe 11 for use, and the rainwater may be insufficiently sterilized; 9. Wait for a certain reaction time after the disinfectant is introduced into the interior. At this time, a small amount of rainwater can be released through the external pipe 11 for inspection. The inspection confirms that it has been fully disinfected and then released for use. If the disinfection is not sufficient, continue to wait or add disinfectant.
